NUCLEAR REGULATORY COMMISSION

[Docket Nos. 52-027 and 52-028; NRC-2008-0441]


Virgil C. Summer Nuclear Station, Units 2 and 3; South Carolina 
Electric & Gas Company; South Carolina Public Service Authority Debris 
Screen Related Dimensions

AGENCY: Nuclear Regulatory Commission.

ACTION: Exemption and combined license amendment; issuance.

-----------------------------------------------------------------------

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is granting an 
exemption to allow a departure from the certification information of 
Tier 1 of the generic design control document (DCD) and is issuing 
License Amendment No. 66 to Combined Licenses (COL), NPF-93 and NPF-94. 
The COLs were issued to South Carolina Electric & Gas Company and the 
South Carolina Public Service Authority, (both collectively referred to 
as the licensee) for construction and operation of the Virgil C. Summer 
Nuclear Station (VCSNS) Units 2 and 3, located in Fairfield County, 
South Carolina.
    The granting of the exemption allows the changes to Tier 1 
information asked for in the amendment. Because the acceptability of 
the exemption was determined in part by the acceptability of the 
amendment, the exemption and amendment are being issued concurrently.

DATES: The exemption and amendment were issued on March 27, 2017.

SUPPLEMENTARY INFORMATION: 

[[Page 19756]]

I. Introduction

    The NRC is granting an exemption from Paragraph B of Section III, 
``Scope and Contents,'' of appendix D, ``Design Certification Rule for 
the AP1000,'' to part 52 of title 10 of the Code of Federal Regulations 
(10 CFR), and issuing License Amendment No. 66 to COLs, NP-93 and NPF-
94, to the licensee. The exemption is required by Paragraph A.4 of 
Section VIII, ``Processes for Changes and Departures,'' appendix D, to 
10 CFR part 52 to allow the licensee to depart from Tier 1 information. 
With the requested amendment, the licensee sought proposed changes that 
would revise the Updated Final Safety Analysis Report in the form of 
departures from the incorporated plant-specific DCD Tier 2 information. 
The proposed amendment also involves related changes to plant-specific 
Tier 1 information, with corresponding changes to the associated COL 
Appendix C information. The proposed changes are to information 
identifying the frontal face area and screen surface area for the In-
Containment Refueling Water Storage Tank (IRWST) screens, the location 
and dimensions of the protective plate located above the containment 
recirculation (CR) screens, and increasing the maximum Normal Residual 
Heat Removal System flowrate through the IRWST and CR screens.
    Part of the justification for granting the exemption was provided 
by the review of the amendment. Because the exemption is necessary in 
order to issue the requested license amendment, the NRC granted the 
exemption and issued the amendment concurrently, rather than in 
sequence. This included issuing a combined safety evaluation containing 
the NRC staff's review of both the exemption request and the license 
amendment. The exemption met all applicable regulatory criteria set 
forth in 10 CFR 50.12, 10 CFR 52.7, and Section VIII.A.4 of appendix D 
to 10 CFR part 52. The license amendment was found to be acceptable as 
well. The combined safety evaluation is available in ADAMS under 
Accession No. ML17040A590.
    Identical exemption documents (except for referenced unit numbers 
and license numbers) were issued to the licensee for VCSNS Units 2 and 
3 (COLs NPF-93 and NPF-94). The exemption documents for VCSNS Units 2 
and 3 can be found in ADAMS under Accession Nos. ML17040A547 and 
ML17040A553, respectively. The exemption is reproduced (with the 
exception of abbreviated titles and additional citations) in Section II 
of this document. The amendment documents for COLs NPF-93 and NPF-94 
are available in ADAMS under Accession Nos. ML17040A543 and 
ML17040A545, respectively. A summary of the amendment documents is 
provided in Section III of this document.

II. Exemption

    Reproduced below is the exemption document issued to V. C. Summer 
Units 2 and 3. It makes reference to the combined safety evaluation 
that provides the reasoning for the findings made by the NRC (and 
listed under Item 1) in order to grant the exemption:
    1. In an application dated August 12, 2016, the licensee requested 
from the Commission an exemption to allow departures from Tier 1 
information in the certified DCD incorporated by reference in 10 CFR 
part 52, appendix D, as part of License Amendment Request 14-11, 
``Debris Screen Related Dimensions.''
    For the reasons set forth in Section 3.1 of the NRC staff's Safety 
Evaluation, which can be found at ADAMS Accession No. ML17040A590, the 
Commission finds that:
    A. The exemption is authorized by law;
    B. the exemption presents no undue risk to public health and 
safety;
    C. the exemption is consistent with the common defense and 
security;
    D. special circumstances are present in that the application of the 
rule in this circumstance is not necessary to serve the underlying 
purpose of the rule;
    E. the special circumstances outweigh any decrease in safety that 
may result from the reduction in standardization caused by the 
exemption; and
    F. the exemption will not result in a significant decrease in the 
level of safety otherwise provided by the design.
    2. Accordingly, the licensee is granted an exemption from the 
certified DCD Tier 1 information, with corresponding changes to 
Appendix C of the Facility COLs as described in the licensee's request 
dated August 12, 2016. This exemption is related to, and necessary for, 
the granting of License Amendment No. 66, which is being issued 
concurrently with this exemption.
    3. As explained in Section 5.0 of the NRC staff's Safety Evaluation 
this exemption meets the eligibility criteria for categorical exclusion 
set forth in 10 CFR 51.22(c)(9). Therefore, pursuant to 10 CFR 
51.22(b), no environmental impact statement or environmental assessment 
needs to be prepared in connection with the issuance of the exemption.
    4. This exemption is effective as of the date of its issuance.

III. License Amendment Request

    By letter dated August 12, 2016, the licensee requested that the 
NRC amend the COLs for VCSNS, Units 2 and 3, COLs NPF-93 and NPF-94. 
The proposed amendment is described in Section I of this Federal 
Register notice.
    The Commission has determined for these amendments that the 
application complies with the standards and requirements of the Atomic 
Energy Act of 1954, as amended (the Act), and the Commission's rules 
and regulations. The Commission has made appropriate findings as 
required by the Act and the Commission's rules and regulations in 10 
CFR chapter I, which are set forth in the license amendment.
    A notice of consideration of issuance of amendment to facility 
operating license or combined license, as applicable, proposed no 
significant hazards consideration determination, and opportunity for a 
hearing in connection with these actions, was published in the Federal 
Register on October 11, 2016 (81 FR 70182). No comments were received 
during the 30-day comment period.
    The Commission has determined that these amendments satisfy the 
criteria for categorical exclusion in accordance with 10 CFR 51.22. 
Therefore, pursuant to 10 CFR 51.22(b), no environmental impact 
statement or environmental assessment need be prepared for these 
amendments.

IV. Conclusion

    Using the reasons set forth in the combined safety evaluation, the 
staff granted the exemption and issued the amendment that the licensee 
requested on August 12, 2016.
    The exemption and amendment were issued on March 27, 2017, as part 
of a combined package to the licensee (ADAMS Accession No. 
ML17040A530).

    Dated at Rockville, Maryland, this 17th day of April 2017.

    For the Nuclear Regulatory Commission.
Jennifer Dixon-Herrity,
 Chief, Licensing Branch 4, Division of New Reactor Licensing, Office 
of New Reactors.
